It is a world where the necromancer, Pirwa, extends his power over the remaining kingdoms using the cruel butchery of his undead 'gravers'. Pirwa plans to unleash his hordes upon the last two bastions of those who follow the ways of the Chara. The fortress island of Charax is one spot that stands in the way of the necromancer. However, the fortress is much like the society, a decaying symbol of the past. Strict social and economic stratification allows the Chara to control the island along with the help of pirates who dominate the waters. When an offer of quick wealth leads Hilko, a young smuggler, into his betrayal. The man uses his ability to communicate with ghosts to aid in his escape. Ending up on a ship filled with pirates, Hilko slowly understands the power of the object he's stolen. In his quest to avoid the 'gravers' and comrades with ulterior motives, Hilko discovers that true friendship and loyalty can come from any social class, living and dead.
